Replaced iPhone4 battery. Now randomly restarts and battery % broken!
My wife's iPhone4 (AT&T) battery was draining very quickly so we bought a replacement through iFixIt.com. I followed the steps exactly, and thought I had performed the upgrade perfectly. Now we are running into issues.
First off, the battery % indicator doesn't seem to increase when on the charger. For example, my wife had 55% battery power when she went to sleep and put the phone on the charger. When she woke up, still 55%. She restarted the phone, which then dropped the battery level to 22% (even though it had been on the charger all night).
Now the phone is randomly restarting by going black, then immediately to the startup screen (white Apple logo). It restarts very often.
Obviously something is very wrong. Could it be that the battery we received was a lemon? I had no trouble with the installation. The phone does make and receive calls, when it's not randomly restarting.
I reinstalled the old "quick to drain" battery, and the problems stopped. The phone no longer randomly restarts, and the battery indicator level (%) does increase while being charged. It's looking like the new battery itself is the issue.
Please help! My wife can't live without her iPhone.
the new battery is not the original one . i already faced this problem . i have changed the battery on iphone4 with the cheap market. after installing battery phone not charging the battery as same as remained charged. battery percentage is not increasing . but after changing the battery again with the original problem solved. the original battery i pulled form working phone. just change the battery. it will solve your also problem.
Before you go and start huffing and puffing about the bad batteries make sure you have some settings disabled first! :P
WiFi - This is the No.1 cause of minimal battery life. A lot of people leave this bad boy on when they aren't even using it, or they don't even realise it is on in the first place. The common mistake people make with this is they presume the WiFi is off when it says
That purely means it is not connected to a wifi router, it does not mean it is physically turned OFF. It still in fact runs at full battery draining capacity because it is constantly searching for new/old networks to connect to.
To solve this issue, make sure this setting is switched to
NOTE - After you update/restore your iPhone, the default factory settings are enabled and good old WiFi is enabled again. Also try to only use WiFi where there are power supplies to recharge your iPhone with.
Bluetooth - Make sure this sucker is disabled as well. Unless you are in your car using it for handsfree or at home using it for music, KEEP IT OFF.

I replaced my battery and had the same problem.
But I did resolve it.
After I installed the new battery I turned it on. Then I held the sleep button and home button at the same time. I ignored the slide to turn off. Continued to hold it till the apple logo reappeared (took about a minute). This is performs the function of a reset which is not the same as just turning it off and back on.
No, I did not order a battery elsewhere. Didn't want to waste any more time on the subject, and by that point in time we had resoled ourselves to using it as plugged in ipod and got a new phone instead.
Though, thinking back at it, I think the third battery was fine, but the issue was that the phone would not do iOS software updates, something in the process where it complained about not original components. Which is when iFixit support called it quits too. Probably some little part number that didn't match with what it came with from the factory. Installed the old battery, updated fine. I don't remember at this point if I then opened the phone up again to reinstall the last ifixit battery.
So part matching is critically important. But, some of the replacement parts / batteries have been sitting on the shelf at iFixit for a while. I would need to check my mail logs to see what all I ran into.
I just wanted to help anyone out there having the same problem.
I also had the same problem. My phone keeps on restarting even when the charger is plugged. I also noticed that the battery percentage is stuck and no longer displays the correct value. I was searching the internet for a solution but all were saying to replace the battery or reset the phone. I already tried resetting the phone but it didn't work.
Out of frustration, i was just ranting to my friends that my iphone is breaking down. Then one of them suggested to turn off the battery percentage display. This seems to have solved my problem. My phone is no longer restarting and I didn't have to replace the battery.
Give it a try first before replacing the battery or replacing your phone. Might save you some money.
Let me know your feedback.
Hey everyone, what I found was that my phone was doing the same things. I took the back off, examined the battery, plugged in the charger and the phone turned on fine. Everytime I tried to put the cover plate on the phone it would shut off. After looking closely, I noticed a tiny nick in the black rubberized insulation on the connector from the battery to where it connects to the phone. I covered it with a tiny piece of electrical tape, closed the phone back up and no problems at all. Yes electrical tape meet iphone. Now for my paperclip trick.
